AI Technical Summary

Technical Problem

Existing view-through optics, such as riflescopes and binoculars, face challenges in achieving best focus for displayed information due to large relay optical designs that lead to aberrations and defocusing at the edges, and these designs are costly and difficult to assemble, limiting the use of corrective optical surfaces like off-axis, freeform, or aspheric elements.

Method used

The implementation of a relay optic design that replaces traditional mirror/lens arrangements with prism/integrated elements, incorporating a prism element with multiple optical surfaces for magnification, beam control, and aberration control, and a mounting system with adjustable screws and biasing members to align the display correctly, allowing for better focus control and misalignment correction.

Benefits of technology

This solution enables high-resolution image overlay in the field of view with improved optical quality, reduced size and weight, and easier manufacturing, while integrating multiple optical functions into fewer elements, thus enhancing the display's clarity and reducing production costs.
